To calculate the area of a circle, you can use the formula:
\[ \text{Area} = \pi r^2 \]
where \( r \) is the radius and \( \pi \) is approximately 3.14.
In this case, the radius \( r = 98 \) mm.
\[ \text{Area} = 3.14 \times (98)^2 \]
Calculating \( (98)^2 \):
\[ (98)^2 = 9604 \]
Now, substituting back into the area formula:
\[ \text{Area} = 3.14 \times 9604 \]
Calculating this:
\[ \text{Area} = 30159.56 \]
Rounding to the hundredths place:
\[ \text{Area} \approx 30159.56 \text{ mm}^2 \]
Therefore, the area of the circle is
\[ 30159.56 \text{ mm}^2 \]
